Hi Kendo Team,
After we updated to version 2022.2.301 we decided to modify our theme by compiling the Metro theme from the source files and adjusting some of the variables provided.
When checking on the styles of the date-time-picker we noticed that the focused column of the time picker would not be highlighted anymore. Also the title would not get the darker color it had in the previous version (see attached image)
We noticed that in v2022.2.301 the focus class has changed from 'k-state-focused' to 'k-focus' (see inspector screenshot)
The styles in the files 'web/common/inputs.less' and 'web/type-metro.less' on the other hand still refer to the class .k-time-list-wrapper..k-state-focused to style title and the ::before and ::after elements that define the background color.
We will add styles to our custom file to correct this. The question for future updates would be though, which class will be the preferred one to keep.
